Nemesia plant named ‘KLENH08454’

ABSTRACT

A new cultivar of  Nemesia  named ‘KLENH08454’ particularly characterized by red-purple flowers with purple eyes and orange nectar guides, good branching, and a vigorous growth habit, is disclosed.

Genus and species: Nemesia hybrida.

Variety denomination: ‘KLENH08454’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Nemesia,botanically known as Nemesia hybrida, and hereinafter referred to by thecultivar name ‘KLENH08454’. ‘KLENH08454’ originated from a controlledcross made in June 2005 in Stuttgart, Germany between the proprietaryfemale Nemesia plant ‘NH050105’ (unpatented) and the proprietary maleNemesia plant ‘NH050108’ (unpatented). A single plant selection wassubsequently chosen for further evaluation and for asexual propagation.

The new cultivar was first propagated in September 2006 by vegetativecuttings in Stuttgart, Germany and has been asexually reproducedrepeatedly by vegetative cuttings and in-vitro propagation in Stuttgart,Germany for about a two and one-half year period (about sixgenerations). ‘KLENH08454’ has been found to retain its distinctivecharacteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normal commercialpractices in a greenhouse in Stuttgart, Germany.

-   -   1. Red-purple flowers with purple eyes and orange nectar guides;    -   2. Good branching; and    -   3. A vigorous growth habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Nemesia plant is illustrated by the accompanying photographwhich shows a close-up of flowers and buds. The colors shown are as trueas can be reasonably obtained by conventional photographic procedures.The photograph is of a plant about 18-weeks old and grown from rootedcuttings in 10.5 cm pots in a greenhouse (glasshouse) in Stuttgart,Germany in spring 2008 under conditions which approximate thosegenerally used in commercial practice.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctivecharacteristics of ‘KLENH08454’. The data which define thesecharacteristics were collected from asexual reproductions carried out inStuttgart, Germany. The plant history was taken on 18-week old plants in10.5 cm pots that were pinched once after 10 weeks and grown in agreenhouse in spring 2008. The color readings were determined undernatural light. Color references are to The R.H.S. Colour Chart of TheRoyal Horticultural Society of London (R.H.S.) (2001).
